FRANK E. WILKINSON AND JACOB CHARLES MoNAUGI-IT, OF KINGFISHER, OKLAHOMA.

DUST-MULSH MACHINE.

Application filed May 23, 1917.

To all whom it may concern:

Be it known that we, FRANK E. WILKIN- SON and JAcoB OHARLEs MONAUGHT, citizens of the United States, residing at Kingfisher, in the county of Kingfisher, State of Oklahoma, have invented a new and useful Dust-Mulsh Machine, of which the follow- 1113' is a specification.

This invention relates to cultivators of that type known as dust mulsh machines, one of the objects of the invention being to provide a machine of this character which is simple and compact in construction, can

be easilymoved from place to place, and

which utilizes a cultivating blade of novel form designed to out under the surface'of the ground to produce the desired mulsh.

A further object is to provide a blade of this character having means whereby weeds and trash are prevented from accumulating about the end portions of the blade and interfering with the operation of the machine.

A further object is to provide a cultivator of this .type which can be adjusted to meet diiferent requirements.

A still further object is to provide means, extending from the blade of the cultivator, for breaking up the soil passing over the blade and for throwing upwardly from the soil any roots, trash, and the like which may be loosened by the blade.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of the parts in the details of construction and hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings I Figure 1 is a side elevation of the machine.

Fig. 2 is a plan view.

Fig. 3 is a section online 33 Fig. 1.

Fig. 4 is a detail view of some of the lifting fingers.

Referring to the figures by characters of reference 1 designates the body of the machine, which, as shown, may be mounted on runners although it is to be understood that,

Serial No. 170,498.

if preferred, the machine may be supported by wheels. Arranged transversely on the body of the machine is a shaft 2 adapted to be rotated by a hand lever 3 which is secured thereto, this lever carrying a dog 4: for engagement with a toothed segment '5.

F ixedly secured to the shaft are radial arms '6 and these arms are connected, by links 7, to the up turned ends 8 of a cultivating blade 9. In the structure illustrated the blade 9 is formed in a single strip of metal having astraight front edge which is sharpened, the end portions of the strip being bent at right angles and provided with apertures 10 any one of which is adapted to receive the bolt 11 employed for attaching a link '7 to the blade. The bolt 11, as well as additional bolts 12 may be employed for fixedly attaching to the up turned end 8 guide arms 13 which extend forwardly and arepivotally connected to the body structure 1 as indicated at 14:. These arms 13 maybe used to support disk colters 15 and in addition to these disk colters, colter blades 16 may be adjustably connected to the up turned ends 8 of the blade 9. If preferred either of the colters can be used independently of the other, and in any direction or at any angle. a

The prime object of the colters is to cut or remove trash and weeds which may lie in the paths of the up turned ends 8 and to clear them away from said ends so that the blade 9 and its ends will cut readily through the soil thereby loosening it to produce the desired dust mulsh. Obviously instead of providing the colters close to and directly in front of the ends 8 of the blade, they could be mounted adjacent the front end of the body 1 but in the path of the ends 8 of the blade 9.

For the purpose of breaking up the slice of soil above the blade 9 and elevating to the surface of the soil any weeds, roots, trash or the like, a series of upwardly extending fingers 17 is provided. These fingers are extended from a metal strip 18 which is riveted or otherwise secured to the bottom of the blade 9 near its rear edge. Obviously, therefore, as the blade cuts through the soil, the slice of soil passing thereover will be broken up by the fingers l7 and any trash, roots or the like coming into contact with the fingers will be directed upwardly thereby. These fingers thus act not only as a barrow for breaking up the soil but also as a means for elevating trash, roots and the like and separating them from the soil. They are particularly useful in digging potatoes and for like purposes.

Not onlyis the front edge of the blade 9 sharpened but the front edges of the ends 8 are likewise sharpened.

When the machine is drawn over the soil the lever 3 can be shifted readily so as to cause the arms 6 and links 7 to press downwardly on the rear ends of the arms 13. This will cause the blade 9 to press downwardly into the soil where it will be held when the lever 3 is locked. Consequently as the machine moves forward the surface portion of the soil will be sliced and broken up into a dust mulsh, interference with the movement of machine by trash and the like being prevented by the colters and by the sharpened front edges of the ends 8.

By means of the adjustment shown, the blade 9 can be placed at any desired angle relative to the arms 13 and, by means of the lever 3, the blade can be forced any desired distance below the surface of the soil. Thus the machine can be adjusted to meet various requirements. v

A machine such as described is capable of a wide range of work, such as cultivating corn, cotton, and tobacco, garden truck, vineyards, orchards, and fields in general. The machines can also be used in harvest- Copies of this patent may be obtained for ing beans, peanuts, onions, cabbages, potatoes, cow peas, etc. While the blade has been shown connected to a portable structure mounted on runners,

it is to be understood that the said blade can be mounted in other manner desired so that it can be used in producing a dust It will also be understood that various changes can be made in the construction and arrangement of parts within the scope of the claim.

What is claimed is:

-A machine for producing a dust mulsh upon a harddry soil, including a flat blade 1 having a front cutting edge, the ends of the blade being upturned and having sharp 5 front edges, a rod connecting said ends, a movable structure, guide arms secured to said ends and pivotally connected to said structure, ground engaging devices .connected to the arms, said structure, and link connections between said mechanism and the ends of the blade.

In testimony that we claim the-foregoing as our own, we havehereto affixed our signatures in the presence of two witnesses.
